Whereas the complexity of alkali-aggregate reaction and in order to guarantee the durability and use security of concrete, it should strictly control the alkali content of cement.
鉴于碱-骨料反应的复杂性，为了确保混凝土的耐久性和使用安全，需要严格控制水泥的含碱量。
Moreover, the alkalinity is low and the alkali-aggregate reaction of the cement concrete is inhibited;
碱度低，可抑制泥凝土碱集料反应；
